PSPKVM is a Java 2 Micro Edition (J2ME) CLDC/MIDP Emulator for the Sony PSP.

Changes:

Streamlined command handling in Virtual boards–all boards now allow direct entry of commands registered by midlet authors without going through the interim text context layer. Semichordal and Danzeff boards also bind appropriate keys to OK and CANCEL command types if the midlet author registers them correctly. Allows single keystroke return from full-screen text fields in many midlets, including Opera Mini. See ‘Fast confirm/cancel’ in the wiki page UsingTheSemichordalBoard (the keys in the Danzeff board look the same).
Added experimental, compact ‘floating’ version of AWF virtual board (see AWFFloat).
Changed colours of Danzeff/semichordal keys to make distinguishing them easier.
AMS warns when you attempt to move a folder into itself or into its own child.
Changed Config midlet ‘Exit’ to ‘Done’.
AMS allows deleting of non-empty folders.
Improvements to smart positioning system in virtual keyboards, so they move properly around one-line textfields in forms.
(non-UI/non-user) added Java interfaces exposing native to J2ME control mapping–necessary to get AWF board operating properly when keys are remapped by user or ‘Western’ X/O mapping is selected.

[+] Bug where emulator would hard-power-off PSP when exiting rather than return to the Xmb is now fixed (both in file menu and main menu)

PSPKVM is a Java 2 Micro Edition (J2ME) CLDC/MIDP Emulator for the Sony PSP.

Changes:

Bugfix: ‘zombie midlet’ bug in which marked, removed midlets would reappear on a subsequent move has been fixed. Loading code has also been modified to allow loading of the folder system in the AMS even after a crash due to this bug. If you got locked out of your VM because of this, using this build will let you back in.
Bugfix: missing utility/symbols file no longer brings down the VM when opening virtual keyboards using it.
Bugfix: unused menu items removed from Danzeff board.
